Butterfield, Steinfeld, Hawke also starring

Production began Monday with the directing team of Bob Pulcini and Shari Berman (“American Splendor”). Producers are Anne Carey and Amy Nauiokas for Archer Gray Productions, Trudie Styler and Celine Rattray for Maven Pictures, and Luca Borghese.

“Ten Thousand Saints,” set in the Lower East Side of New York City in the 1980s, follows three screwed up young people and their equally screwed up parents.

Mortimer will play the mother of Steinfeld’s character and Nicholson will portray the ex-wife of Hawke’s character and the mother of Butterfield’s charachter.

Mortimer is set to star in the third season of HBO’s “The Newsroom.” Nicholson stars in “August: Osage County” and Showtime’s “Masters of Sex.”

Mortimer is repped by ICM, 42 Management, Brillstein Entertainment Partners and attorney David Weber. Nicholson is repped by CAA and Davien Littlefield.
